A user-reported bad call is the most expensive kind of alert. It arrives late, after the customer already had the bad experience. It arrives vague, "it was breaking up." And it arrives without evidence, because the call is over and the conditions that caused it have moved on.
Reactive monitoring waits for something to break and someone to notice. Proactive testing breaks nothing but runs the call for you on a schedule, so you find the fault on a synthetic call before it lands on a real one.
Every support ticket has a hidden cost.
Every user-reported issue carries hidden costs:
Proactive testing removes all four by not depending on a human noticing.
Schedule beats complaint every time.
Synthetic test calls run continuously from the places your users actually are:
| Approach | Reactive | Proactive |
| Trigger | A user complains | A schedule |
| Timing | After the bad call | Before it |
| Evidence | Gone | Captured at the moment of failure |
| Coverage | Only reported issues | Every route, every site, on a cadence |
Run a test call across each critical route on a schedule and a degrading trunk shows up as a failing synthetic call at 3am, not as an angry customer at 9.

Powered by Prognosis, proactive by design.
IR Collaborate, powered by Prognosis, runs synthetic test calls across your VoIP routes on a schedule and measures the quality of each one. Degradation surfaces on a test call before it reaches a customer. When a route starts to fail, you already have the evidence, the location, and the timing—without waiting for anyone to report anything.
Stop learning about problems from the people they hurt.
The goal isn't to respond to bad calls faster. It's to stop learning about them from the people they hurt. Test the system before your customers do, and the first sign of a problem is a failed synthetic call, not a lost account.
Get visibility into your VoIP routes before users report issues. Proactive testing catches degradation early.
